Key Features
- Genuine OEM Electrical Spec — manufactured to Husqvarna's exact switch resistance and contact ratings, not a generic approximation, so ignition circuits respond correctly every time the key is turned
- Direct Plug-In Replacement — engineered to connect directly to the Soff-Cut4000 wiring harness using the original connector configuration, requiring no rewiring or adapter work
- Soff-Cut4000 Compatibility — purpose-built for the Soff-Cut4000 early entry saw, a Kohler-powered green-concrete saw used for early-entry control joint cutting
- Reliable Start and Stop Control — a correctly functioning key switch delivers clean, consistent ignition engagement and ensures the engine shuts down fully when switched off, protecting the operator and the machine
- Electrical Safety Integrity — a worn or failing key switch can cause intermittent starting, unintended engine runoff, or loss of shutdown control; replacing it with the correct OEM part restores safe, predictable machine behavior
The key switch is the primary ignition control on the Soff-Cut4000, governing both engine start and shutdown through a keyed electrical contact. When the switch is turned, it completes or interrupts the ignition circuit, signaling the Kohler engine to start or stop. A damaged or corroded switch can produce erratic starting, prevent the engine from shutting down cleanly, or cause electrical faults elsewhere in the ignition system — making timely replacement essential to safe operation on any concrete cutting site.
